Modbus RTU Slave Serial Gateway Communications
Serial Communication
Built-in peripheral port: PG (including Programming Console) connections, Host Link, NT Link, Serial Gateway (CompoWay / F Master)
Built-in RS-232C Interface: PG (without programming Console) connections, Host Links, no-communication protocol, NT Link, Modbus RTU Slave Serial Gateway (CompoWay / F Master or Modbus Master)
Serial Communications (sold separately): Protocol macros, Host Links, NT Links
So,I would like to present in this.
Serial Gateway (CompoWay / F Master or Modbus Master)
This means that if a Modbus slave (or servo drive, etc.) or CompoWay / F Slave (Temp Control, etc.) is connected to a serial port on the CJ1 and CJ2 PLC, then a host CPU, in conjunction access to port and tunnel through the PLC and connect the port directly to the slave. This makes the programming or software parameter is not directly connected to the Modbus or CompoWay / F slave attached. You must log macro trigger the PLC or Modbus CompoWay / F command to give the slaves.
I can built-in serial interface (Host Link Port) serial communications gateway / Modbus RTU?
It depends on CX-Programmer version I use? (more…)
